To all whom it may concern,.- Would, however, be within our invention to 'Be it known that we, ORLANDO C.

Our invention relates to the construction In the accompanying drawings, Figures l, of metallic wheels; and its object is to pro- 2, 3, and 4 illustrate various parts of -a hub duce a wheel which shall be cheap, rigid, made in accordance with our invention.

Figs. 7, 8, and 9 show various screwed into place on a cast-iron hub. This parts adapted for use in making a wheel havconstruction is not onlya difficult one in maning two rows of spokes. Fig. l0 shows the 2O ufacture, but the imposition of heavy strains llllb-bOX having 3 Hnge fOI USG ill 00111190- 7C on the metal is apt to impairits strength.

These are welded together are exterior to a suppleflanges may be formed on one or both of the mental collar, which holds the spokes in the collars and embrace the flange B, with the spoke grooves or sockets formed in or on the spokes in place thereon. The spokes them- 5o flange projecting from the hub-box. It selves may be formed in anymanner known roo in the art. The collars E may be drop forgings of softiromsteehor other suitable metal.

The spokes having been placed in position in the sockets or grooves in the flange B and the collar C applied, the collars E are applied over the box D and their edges abutted against one anotherand against the spokes, so as to grasp the latter on opposite sides. The part-s are then welded together, by the electric welding process, by passing a heavy electric current through the parts from one collar E to the other, so as to heat the abutting parts to plasticity and then applying end pressure to force the parts together and Weld them to one another. By this procedure the collars, spokes, and flange are forced into veryclose relation with each other and fastened firmly together, the spokes becoming welded to the metal collars E, and the collars themselves being also welded together around the flange B.

It is obvious that the use of the collar C might be dispensed with when other devices are employed for holding the spokes in place against lateral displacement from the spokegrooves or flange or collar B. We prefer, however, to employ the additional collar C, as indicated.

In the remaining` figures of the drawings we have illustrated our invention as applied to a wheel wherein two rows of spokes are eirployed and the additional collar C is omitte Fig. 10 shows the box D as provided with a flan ge or collar B, having spoke-grooves at its opposite edges adapted to receive the two rows of spokes, as indicated in Fig. l1. E E are the collars, which are similar to those before described and which slip upon the hub-box D. E2 is a collar having the spoke-grooves indicated and adapted to slip over the flange or collar B. The width of the collar E2 is a little greater than that of the flange B. The collar E2 having been applied uponthe flange B, thef spokes are put into position in the notches in the flange B and in the collar E2, after which the exterior collars E are slipped upon the hub and broughtinto position against the spokes and into abutment with the collar E2. After this the electric-welding operation before described is resorted to and the collars or sections of hub E E2 finally welded together and to the spokes grasped between them, the whole being held from turning in this case upon the box P by the engagement of the spokes with the spoke-grooves in the flange B.

In constructing a wheel such as illustrated in Fig. 5 the volume of' the electric current employed will to some extent determine the extent to which the parts shall be welded together. The principal welding may be produced between the parts E E, though it may be of course extended so as to include the interior collars C. The principal office, however, of the parts B O is to hold the whole structure against moving upon the hub-box D, while the exterior collars E give strength and rigidity to the whole structure.

`What we claim as our invention is- 1. In a metallic wheel, the combination, with the wlieel-h ub box provided with a flange having spoke grooves or sockets, of two collars fitting on said box and welded. together and to the spokes grasped between them.

2. In a metallic wheel, the combination, with the Wheel-hub box having a flange p rovided with spoke-grooves, of a collar fitting on said box and holding the spokes 1n the grooves, and exterior collars having horizontal flanges welded together and to the spokes grasped between them, as and for the purposes described.

3. A metallic wheel having a wheel-hi'ib box provided with a flange, spokes resting 1n grooves in said flange, and two collars abutted against one another over said flange andu welded together and to the spokes, as and for the purpose described.

4. In a metallic wheel, a hub-box having a flange provided with spoke-grooves, spokes resting in said grooves, and a collar for holding the spokes in the grooves, said collar, flange, and spokes being all welded together, as and for the purpose described.

5. In a metallic wheel, the coinbination'of a wheel-hub box having a flange or collar integral with it and provided with spoke-grooves, and two collars grasping the spokes at opposite sides outside said flange and welded together and to the spokes, as and for the purpose described.

6. In a metallic wheel, a hub having a flange provided with spoke grooves or notches at its opposite ends, a collar fitting over said flange, and two collars fitting upon the hubbox at opposite sides of said flange and welded to the first-named collar and to the spokes, as and for the purpose described.
